T0 all whom it may concern:

Be it known that I, ANDREW C. Das vini, u citizen of the United. States,residing et lProvidence, in the. county of Providence und State ot'Rhode Island, have invented certain new and useful improvements inAuxiliary Oiling Devices Yfor Automobiles, of which the following is o.speeilicution.

My invention relzies to improvements in auxiliary oiling systems forautomobiles, :incl the purpose ol my invention is to pro- .vicie :idevice by whichthe supply olf oil used in lubricating the engi-ne of 2innuto mobile muy be increased in volume so its not to requirereplenishing so often; also to provide for :i circulation of the oilfrom the mein supply to the auxiliary supply und beck again, with ineensot' filtering the same between tl'ie auxiliary toni; und the moin supplytzinl; und especially to provide o Ineens of regulzitiug,1 the oilsupply to the engine so that :in excess 0l' oil may be avoided.

My device is intended to be applied to automobiles of the type in whichthe ily-- wheel oise is used es en oil refiler-voir, and in which theoil is splzisl'ied or driven into the crunk case by ineens ol thespoloxfL-i und rim of the ily-wheel thence Vliowing boeit over thebottom of the cruel: euse to the fly/wheel euse.

l uceoniplisl'i these results with the mechenisni shown in theaccompanying drawing, in Which- Figure l is an elevation of u iirunlcshult, ily-Wheel, und crank onse ot on outoiriobile having my auxiliarysystem utteoheii. liig. 2 is o vertioul long gitudinul section thi-ruwthe auxiliary tunli', :incl Fig. t1, u.

cross-sectioi'i upon the plone r' t Fig. 1l. The saine ports are des :oby the suine letters throughout the sei/emi rlrzrwings..

In lliig. l, t is o, ily-Wheel of un uutonio bile; .s' the crunksluiii't; .cl-ms", otr. the cranks; c represents the ily wheel c2c-,reserving es en oil reservoir in which reservoir the fly-Wheel runs; o-Moboing' the erzinlc case the bottom. oit' which in, automobiles et thistype is flut or level; while c" is the .lei el or iluttcnecl bottom olthe crunk oise, und c-0 o. thickened margin ot' the crank ense vznfoundits lower sui-luce. in most oit the automobiles oi this type, there aredepressions IDC-b', etc., seen best in Fig. Q, into which the lower endof the connecting rod dips when the engine isin operation, and

the oil is supposed 4to flow back by gravity into the reservoir wheelcase c3 after e. ce1'uw tain amount of it has been splashed into thebottom of the crunk case. In practice, however, it is found that thesplashing foi-ee of the {ly-wheel is so greet, especially when theengine is speecled up', that much more oil than is needed is forced intoand kept in the crunk cose thus causing u, smoky exhaust and excessivecarbonizution und sooting ol cylinder and spark plugs. lily device,which is designed to remedy this trouble, consists substontiull' of anauxiliary tenir, or reservoir, (L, bolted to the bottoni of the originalcrank cese (70 by means of the bolts afm-(Z, or in some other securemanner. This auxiliary tunlt a connects with the crunk euse by anopening in. the bottom thereof into which is screwed the tubular nippleshown in section. in Fig. 23, this nipple being;l iuljustubl y securedto the bottom ol the crunk case c by the nut 4. The upper 'portion o'this` nipple is not flush withthe bottom of the crunk ense butprojects/above the sinne as shown in Figs. l, 2 und El; the amount ofprojection deteri'uining thc permanent level oi the oil in the crankcese, und this amount ol projection muy bc vuried by v-.irying thethickness of the washer il.

At the liot'toin oit the nuxiliury tank (l. is the tubulu r projectionor pipe eswc, shown in section in Figs. 2 und 3. This pipe 13m-a* isprovided :it one end with the plug ,o .find ulso has un orilice as, Fig.9 opening into the auxiliary tank a. The bottoni oi the uuniliory teni;when the automobile is level slopes bzioltwzird, .ns is seen, toward theilyu'hei.' euse e und this pipe ogm-o* is conu'itli the bottom of theily-ivlieel nl: euse c by the -connections c--cc, und fi. .letween theauxiliary toni: (i

and. the' lly-whccl coso c ore interposed the check vulve i' und :i`liltcr g 'the purpose of which will be subsequently shown. The inuit (iis also provided with o. glues ,f5-ugo time? .tor the purpose of showingthe level of' the oil therein.

The cheigli' vcil've is provided so that in euse oin :i deecent ol.unusuul steepness the oil will not work its'wuy buck through the bottomol:A the ily/wheelbase c3 into the auxiliary tank u.; while the filterg, consisting, simply of two'llunges inclosing :i Wire nettiny,I otsuitable mesh, provides 'for a constent cleansing of the oil of allsediment und crank case.

The filter, as above stated,i'nsures thev -abrasions of metal from thebottom of the cleanliness' of the oil and isa great im'- pi'o'enientoverthe present system of oiling' in automobiles of the type described fortheA reason 'that Without my device a sudden change of level in theautomobile from descent to ascent Washes Iall sediment ,from the bottomof the crank case c-'0 back into the fly-Wheel case c3 so that metallicparticles are apt to be splashed up ,by the fly.

splashed by the ily-Wheel into the crank case, of means for disposing ofexcess oil in the crank case and returning 1t to the Hy- Wheel case,comprising an auxiliary oiltank below the crank-case, a pipe connectingsaid auxiliary tank with the lower portion or oil'reservoir ofthe'iiy-Wheel case, and mea-ns for delivering oil from the crankcase tosaid auxiliary tank. v

2. The combination with a crank case provided With a fly-wheel case inopen cornmunication with the crank case, and serving as an oil reservoirfrom which oil'is splashed by the fly-Wheel into the crank case, of anauxiliary oil tank below the crank case, an

oil conduit within the auxiliary tank, a pipe connecting one end of saidconduit with the reservoir-portion of' the fly-Wheel case, `and anadjustable outlet in the bottoni of the crank caselfor regulating thedischarge of oil therefrom to said auxiliary tank.

In testimony whereof I aniX my signature in presence of two witnesses.
